Abstract
A diode comprising a semiconductor body delimited by a front surface and including: a first semiconductor region having a first type of conductivity, facing at least in part the front surface; and a second semiconductor region having a second type of conductivity, the second semiconductor region facing at least in part the front surface and surrounding, at a distance, at least part of the first semiconductor region. The diode further includes: a trench, which extends in the semiconductor body starting from the front surface, for surrounding at least part of the second semiconductor region; and a lateral insulation region, which is arranged within the trench, is formed by dielectric material and contacts at least in part the second semiconductor region.
